Mechanism.
Background technology
Cycloidal planetary gear speed reducer due to have the advantages that speed reducing ratio is big and small volume and progressively substitute gear reduction unit and snail
Bar reductor, and be widely used in as driving or deceleration device in the conversion equipment of speed and moment of torsion.
Cycloidal planetary gear speed reducer is a kind of novel transmission dress applied planetary drive principle, engaged using cycloidal pin teeth
Put, its deceleration transmission part is using circle-arc tooth and needle roller Cylindrical Surfaces Contact, still, because the power of reductor transmits contact surface
Motion process is moved in the form of high load capacity, therefore easily causes abrasion.And its is complicated, requirement on machining accuracy is high,
Certain process gap is left during design and installation, rotates not steady enough when causing work, noise is big, rotational efficienty
It is low, so being necessary to propose a kind of new cycloid speed reducer to solve the above problems now.
In the prior art, the cycloid ball reductor being driven based on ball-shaped ball is compared to traditional cycloidal-pin wheel
Reductor, have compared with much progress in transmission accuracy etc., the China Patent Publication No. referring to the applicant's earlier application is CN
106352043 A's《Trailing type drives reductor》.
But the trailing type of program driving transmission scheme of the reductor based on spheroidal ball, still suffer from problems with：
1. sphere transmission torsion reduces transmission power；
2. know by mechanical analysis：The transmission of power is concentrated mainly on the edge of groove between ball and cycloid groove, and ball is in groove
Middle movement, result are that the abrasion of the abrasion and ball at groove edge are big.
The place that 3. cycloid groove is reductor and its important core technology is concentrated, if premature abrasion here, it will increase
The noise of acceleration and deceleration machine, transmission power is reduced, reduce service life.
Utility model content
The utility model embodiment technical problem to be solved is, there is provided a kind of transmission power is big, to cycloidal path
Groove wears the small reductor cyclo drive mechanism based on tapper part.
To achieve the above object, the technical solution of the utility model is to include cycloid disc, driving member and output panel, described
Cycloid disc be provided centrally with input shaft mounting hole, now with for exporting shaft mounting hole in output panel, it is characterised in that：Institute
The driving member stated is tapper part, and the tapper part is that four angles of rhombic quadrangles are diagonal along its longitudinal direction again by radius r progress roundings angle
Line rotates a circle the rotary body of gained, is provided with circumference uniform distribution in described output panel side card and is provided with tapper part and fixes
Hole, the quantity of tapper part is consistent with tapper part fixing hole, along its longitudinal diagonal on tapper part fixing hole and tapper part
The outline shape size of one end is adapted, and described cycloid disc, which corresponds to, is provided with cycloidal path groove in the card of output panel side,
The cycloidal path groove includes multiple tapper part activity caulking grooves uniformly at intervals, tapper part activity caulking groove and tapper part along its longitudinal direction
The outline shape size of diagonal one end is adapted, and the tooth number Z 1 of tapper part activity caulking groove is less than the quantity Z2 of tapper part；
Side setting-in of the described tapper part along its longitudinal diagonal is fixed on tapper part fixing hole, described tapper
The cycloidal path groove sliding guiding of opposite side and cycloid disc of the part along its longitudinal diagonal is actively coupled.
It is that the tooth number Z 1 of tapper part activity caulking groove and the quantity Z2 of tapper part meet below equation further to set：
Z2 = Z1 + 1。
Further setting is that the coning angle a of described tapper part is：19°< a < 121°.
Further setting is that the horizontal catercorner length of described tapper part is d, and longitudinal catercorner length is c, described
c/d=1.2-3。
It is that the ratio that described chamfer radius r and horizontal catercorner length are d is further to set：2*r/d<0.5.
It is being shaped as described tapper part activity caulking groove section further to set：The drift angle of isosceles triangle presses radius r
Carry out rounding angle.
Innovation Mechanism of the present utility model and advantage are：Substitute circular ball using tapper part, tapper part is indulged along it
To the both sides of diagonal respectively with tapper part fixing hole and cycloidal path groove mutually by power cooperation, compared to spherical ball,
Its forced contact area is bigger, therefore, can be adapted to higher transmission power, in addition, this arrangement enhances tapper part and cycloid
Contact area of the track groove in rotation process is slid, so as to which institute's driving force is not concentrated in the groove of cycloidal path groove on mechanics
Edge, so as to reduce its abrasion, improve its service life, and effectively reduce noise.
